Refinement of the geodynamic situation in the area of the Lena River delta is relevant for understanding local geological processes. Previously, source seismology for this area was provided only by remote regional seismic stations. This paper shows t

Manual processing of large volumes of continuous observations produced by local seismic networks takes a lot of time, therefore, to solve this problem, automatic algorithms for detecting seismic events are used. Deterministic methods for solving the

For seismic observations in mines or wells, instead of three-component geophones, four-component ones with sensors located along the tetrahedral axes are sometimes used. When a geophone is placed in a hard-to-reach area for a long time, the requireme
